The class does not contain a definition for 'DatePicker1'
Hi,

In my asp.net 2.0 web application, I added the DatePicker control to the toolbox and dragged it to a web form. But when I need to get its value in the btnSubmit_Click(), I got an error message:
'namespace1.form1' does not contain a definition for 'DatePicker1'.
I tried to add a line at the begining: using EclipseWebSolutions.DatePicker;
but it does not help. Did I miss something here?

Thanks in advance,

I have not seen that before. Please post or email me your code and/or the full error message. I suggest that you also look at the demo application.

Re: The class does not contain a definition for 'DatePicker1'
Here is what I did. I created a bin folder under foo/foo (suppose my asp.net 2.0 application name is foo), and copy the assembly EclipseWebSolutions.DatePicker.dll to foo/foo/bin/. Then added the DatePicker Control to the Visual Studio toolbox, and then dragged it to a web form.

I guess the first time when I dragged the DatePicker to the form, I got a message to say 'Web.config has been modified outside of the source editor, do you want to reload?'. I clicked the wrong button to reload it so that I lost the changes to Web.config file.

If I manually add the following line to Web.config (same as in your demo) :

then I got a long list of errors, the first one is:
'Could not find schema information for the element 'http://schemas.microsoft.com/.NetConfiguration/v2.0:configuratopn'.

I found Version=1.0.61025.0 does not match the version of EclipseWebSolutions.DatePicker.dll (2.1.2581.35733), I tried 2.1.2581.35733, but it's still same thing.

I guess since I lost the changes in Web.config, that’s the reason I got message:
'namespace1.class1' does not contain a definition for 'DatePicker1'.
How do I add this assembly to Web.config?

Many Thanks,

Re: The class does not contain a definition for 'DatePicker1'
You should not need to add anything to the web.config to support the datepicker. Just add it to the toolbox and drag it onto your form. I think the problems may not be related to the DatePicker. Have you tried creating a clean project and trying to get it to work?

Re: The class does not contain a definition for 'DatePicker1'
You’re right. The problem is not related to the Date Picker. I created a new form and only put a Date Picker, a label, and a button onto it and then it worked perfect. But When I added the master page to this form, then the calendar did not move to the previous or next month when I clicked < or > (it would be closes). Do you have any idea about this issue?

Many Thanks,

Here is my simple form with the master page:

<%@ Page Language="C#" MasterPageFile="~/MasterDaqi.Master" AutoEventWireup="true" CodeBehind="Test2Frm.aspx.cs" Inherits="Appeals.Test2Frm" Theme="myThemes" %>

<%@ Register Assembly="EclipseWebSolutions.DatePicker" Namespace="EclipseWebSolutions.DatePicker"
TagPrefix="cc1" %>

Re: The class does not contain a definition for 'DatePicker1'
Try this example of using the datepicker with a masterpage. I don't know if it will help. I was not able to reproduce your issue.

Re: The class does not contain a definition for 'DatePicker1'
Based on your example, I added all my items to the master page one by one, and it worked perfect. I think a tag that was not organized well caused the problem. Thanks a lot for your help.

One more question to you: When I try to run your demo, I unzipped the files to C:\ews_datepicker. Then open web site C:\ews_datepicker through VS 2005, then highlight Default.aspx, and click the Start button to run it. But I got a message:

Unable to update auto-refresh reference 'eclipsewebsolutions.datepicker.dll'. Cannot find assembly 'C:\code\DatePicker_Source\bin\Debug\EclipsWebSolutions.DatePicker.dll'.

Did I do something wrong here? Any idea about this one?

Many Thanks,

Re: The class does not contain a definition for 'DatePicker1'
That message should be a warning not an error. On my computer if the EclipsWebSolutions.DatePicker.dll file is changed the test project that I sent you will automatically copy it. Obviously when you run it C:\code\DatePicker_Source\bin\Debug\EclipsWebSolutions.DatePicker.dll is not there so it can't automatically update the dll. If you look in the bin directory you should see a file called EclipsWebSolutions.DatePicker.dll.refresh. This is the file that contains the incorrect path. If you delete it I think the message will go away. Glad it is working for you.

Re: The class does not contain a definition for 'DatePicker1'
I think I need to install asp.net AJAX to run your demo.
Thank you very much for all your helps,

The master pages demo I sent yesterday does not use AJAX.
